DHCP Problem - I think??

I am running SBS 2003 SP1 and have recently noticed in the logs that I am
getting event ID 1020 that states I have 0 IP addresses left to hand out
from my scope. I run a network with only about 20 clients and had the scope
set to give out 100 IPs. I have extended the scope and I don't get that
error anymore, but upon further investigation I have realized that the
"type" of ip addresses taking up all the leases are DHCP/BOOTP. Has anyone
seen this or know what may be causing it as I can't seem to figure why all
my ips keep getting leased.

Thank in advance!

Click on the advanced tab for your scope and select DHCP only. Should take
care of it. You've likely got something on your network trying to use bootp.

Re: DHCP Problem - I think??

The weird thing is though is that I have DHCP only selected. All the
"normal" looking leases say DHCP as the type and all the others say
DHCP/BOOTP. How is it allowing that if I have DHCP only checked?

Check to make sure you don't have some RRAS, dial or VPN, "servers"
grabbing sets of addresses.

Re: DHCP Problem - I think??

Thanks for the response, but how might I check this? Would OWA or Remote Web
Workplace be causing this? I have deleted all of the suspect ip leases this
morning and none have come back as of yet.

I don't know this (RWW) but seriously doubt it. RRAS VPN
servers have caused it many times.

On a server open the RRAS console and first JUST LOOK to
see if RRAS is "on" (enabled) -- if not, then this is not the cause
on THAT SPECIFIC server.

Maybe it is just an artifact of some old issues that are gone.

Re: DHCP Problem - I think??

I have never set up RRAS and that service is disabled. Hopefully it was a
one time thing and will not re-appear, but not knowing what caused it is
disconcerting. Thanks.

It was only one of the (likely) possibilities. Do note however that
ANY computer acting as an RRAS (dial or VPN) server on your
network (within a subnet covered by the DHCP scope) can
request these blocks of addresses.

SBS sets this up normaly, so you might have it already. By default SBS RRAS
will grab 10 or 11? addresses from the scope.

In the address leases you have two columns of interest."Type" and "Unique
ID"

If you can post a couple of these as examples, perhaps we can make more
sense of what's happening.

Re: DHCP Problem - I think??

As of now, none of the suspect IP's have returned after I deleted them. If
they do, I will post what I see.

Thanks.
